Abstract: An LED bulb applicable for industrial automated production includes a bulb body, a lamp holder, an LED driving module, a lamp pole, and a light strip. The bulb body is coupled to the lamp holder. The bulb body is made of a transparent material and in a hollow spherical shape. The lamp pole is installed and integrally fixed into the bulb body. The light strips are installed on the lamp pole and formed into a lamp module, and the light strips are connected in series or in parallel with each other. The LED driving module has a hole at the center sheathed on the lamp pole, so that the LED driving module is disposed in the bulb body. The invention has a simple structure and builds in the LED driving module to simplify the manufacturing procedure and lower the level of difficulty of the manufacture.

Abstract: A fully-sealed LED decorative lamp used in festivals includes a bulb shell, a core column, a driving circuit board, an LED lamp body, and a lamp cap. The lamp cap and bulb shell are configured to form a sealed cavity. The core column is partially plugged and fixed into the bulb shell. This invention has the features of powerful function, simple structure, and reasonable design and uses a cup shaped groove filled with colloid and the structure of the LED lamp body to achieve the effect of sealing the light emitting circuit completely, so that the implementation of the present invention can prevent people from being exposed to electric shock after the bulb shell broken and the invention also can prevent short circuit or fire caused by the short circuit, so as to meet the safety regulation and requirement as set forth by the Article UL 588.

Abstract: LED lamp beads with multiple light-emitting points comprising a certain number of luminous bodies and package resins; in which after at least two luminous bodies are connected in parallel, they are wrapped in a package resin and connected to an anode pin and a cathode pin inserted into the package resin. The present invention structure is simple and has a rational design. By using one-way conductive luminance on the LED luminous bodies, and using parallel and inverse parallel connections on multiple light-emitting points, control of the electric current direction is achieved, and thus the control of the operating modes of luminous bodies and the LED lamp beads with multiple light-emitting points is achieved.
